Answer
Use queues like Bull or BeeQueue, or worker threads. Implement retries, DLQs, scheduling, and monitoring.
Quick Answer
Reliable background jobs: use a queue (Bull, BullMQ with Redis) to persist jobs — if the server crashes, jobs aren't lost. Add retries with exponential backoff for transient failures. Use job deduplication to prevent duplicate work. Monitor job queue depth as a health metric. For critical jobs, use at-least-once delivery with idempotent job handlers.
